You nailed it Simon Gunson.You were right from the very beginning dear friend.

In December 2015 the ATSB reported massive electrical failure before 18:03 UTC was why the SDU satellite antenna was out of action until 18:25 UTC.

The Left AC transfer relay did not power the SDU. On a Boeing 777 the Right Integrated Drive Generator is designed to kick in automatically to power the Left AC relay during a failure by the closure of a circuit tie breaker.

If the Tie breaker did not close then the failure was across both Left and Right Bus relays. in that case the Standby Transfer Relay kicked in. The Standby relay will power the autopilot but it will not power the AIMS navigation brain.

Without navigation MH370 could not have navigated through the Straits of Malacca and could not have made precise turns to intercept waypoint VAMPI and then turn to intercept waypoint MEKAR as Malaysia claims military radar observed.

Satellite data does not necessarily corroborate a detour west around Sumatra. Some of the data between 18:25 and 18:28 UTC is highly erroneous. It maybe that the satellite data is erroneous because of electrical failures on MH370.

Malaysia has always refused to prove these radar sightings. The Government therefore can’t prove indeterminate cause of MH370’s loss as grounds for strike out as it has not proved MH370 detoured through the Straits at all. In fact the malaysian Government has introduced what appears to be falsified evidence to mislead the investigation of MH370.

If the Government itself is the author of false evidence then it cannot refute the claims of others as vexatious or frivolous.
